Instance Configuration Requirements

Overview:

When setting up your AWS instance, you’ll need to configure a few key options. Here’s a detailed guide on the recommended configurations and selections.

1. Instance Type

For optimal performance, we recommend using the following instance types:

t3a.small – 2 virtual CPUs and 2 GB memory.
t3.small – 2 virtual CPUs and 2 GB memory.

However, you can choose an instance type based on your specific workload and traffic needs. Here’s a quick reference table to help you decide:

CPU/Memory	Database	Monitored Hosts
1 CPU core / 1 GB	MySQL InnoDB	100
2 CPU cores / 2 GB	MySQL InnoDB	500
4 CPU cores / 8 GB	RAID10 MySQL InnoDB or PostgreSQL	> 1,000
8 CPU cores / 16 GB	Fast RAID10 MySQL InnoDB or PostgreSQL	> 10,000

For more details on different instance types and configurations, refer to the AWS Instance Types documentation.

2. Storage Space

The default allocated storage size for our AMI. You may specify the necessary storage size when launching a new instance or change it after deployment.

20 GB (recommended)

3. Ports Configuration

To ensure smooth operation of your installation, it’s important to open the appropriate inbound and outbound ports. Below are the recommended port settings, though you may configure them based on your specific security group requirements:

Inbound Ports:

Type	Protocol	Port Range	Destination
SSH	TCP	22	0.0.0.0/0
HTTP	TCP	80	0.0.0.0/0
HTTPS	TCP	443	0.0.0.0/0
MySQL/MariaDB	TCP	3306	0.0.0.0/0
CUSTOM	TCP	9090	0.0.0.0/0

(Optional, you may use external relay)
SMTP	TCP	587	0.0.0.0/0
SMTPS	TCP	465	0.0.0.0/0
POP3	TCP	110	0.0.0.0/0
POP3S	TCP	995	0.0.0.0/0
IMAP	TCP	143	0.0.0.0/0
IMAPS	TCP	993	0.0.0.0/0

Outbound Ports:

Type	Protocol	Port Range	Destination
All traffic	All	All	0.0.0.0/0
